Zhang Yi came out of the palace in a daze, and the old bell hurriedly greeted him. It wasn't until he got into his own carriage that Zhang Yi felt a little more comfortable.

He finally compromised with Li Er, because of Li Hui, because of the child in Li Hui's belly, so he compromised, he must marry Li Hui.

In fact, relatively speaking, the Turks and Tibetans, the Turks are more difficult to deal with, whether it is in terms of weapons and equipment, or the number of personnel, even the number of war horses and various systems, the Turks are better than the Tibetans.

However, one of the particularly bad things about fighting Tibet is that the terrain and climate are too restrictive.

When the Tang army attacked the Tang army, it could swoop down from the plateau, but if the Tang army attacked the Tang army, it would have to raise its head and rush from the low to the high.

This not only exerts a lot of physical strength on the Tang army, but also the oxygen content of the plateau is relatively low, and it is easy for the soldiers to go into shock.

In ancient times, the gap in weapons was not big enough to exceed the level of natural conditions, so even if the Tang army hated the Turks, they still had the strength to fight, and even now the Tang army has defeated the powerful Turks.

However, the Tang army was not very willing to attack Tibet, because of countless unsuccessful returns, they were not interested in attacking Tibet.

Now that the Tang army has defeated the Turks, the limelight is flourishing, but the Tibetans are still not worried that the Tang army will attack them, but take advantage of the Tang army's great victory to plunder the Tang people on the border between the two countries.

The continuous emergency reports on the border annoyed Li Er, who had just finished fighting the Turks, and before he had time to celebrate, the Tubo people over there began to do things again.

And when he was upset, he naturally remembered Zhang Yi's remarks, using the power of the economy to disintegrate the fighting spirit of the Tubo people.

Although Li Er also won this piece of the world by conquest, he also has a very deep understanding of the power of the economy.

The economy of every era is developing, and at this time, the people's lives are inseparable from the economy, to the big one, the economically strong country can bully the poor country, to the small one, the people are actually very realistic, whoever can let them eat enough, they will follow that person with all their hearts.

And Zhang Yi's theory, taking advantage of what the Tang Dynasty can now produce but which Tubo lacks, provides it to Tubo cheaply, and the Tubo people will naturally be overjoyed when they get such great benefits.

For example, salt, compared to their high manufacturing costs, Datang provides them at a low price, so they will naturally choose to interrupt the manufacturing and accept these gifts from Datang calmly.

And the amount of salt that Datang provides to them every time can't be too much, it's best to just maintain it on their domestic balance line, and they can't let them have a surplus, and if they can't have a surplus, they can't hoard salt.

Datang can provide salt at a low price, and the Tubo people will definitely not make salt again, in the long run, their salt supply chain will inevitably be broken, and the amount of salt supplied by the Datang group cannot allow them to hoard salt.

Once a person can't eat salt, it only takes a few days, and he will immediately have yellow muscles and thin muscles, the whole person will be listless, and even many people will have some diseases.

The soldiers had no salt to eat and had no way to fight, while the people had no salt to eat, so they either waited to die or rose up to rebel.

When the time comes, the Tang Dynasty will interrupt the supply of salt to Tubo, then the Tubo people can really only bow down, of course, they can also choose to resist, but the final result, it is difficult to say, in short, it will not be better than the result of the first choice.

Chang'an is more than an hour away from Zhangjiazhuang, and in this more than an hour, Zhang Yi has already sorted it out.

The wedding date between him and Xu Rou was set for half a month later, Li Er had already sent someone to inform the Xu family, Zhang Yi felt that it was very necessary for him to take some time to visit the Xu Mansion, no matter what, since he couldn't push it off, he could only accept it calmly, and next, he had to have a good relationship with the Xu family.

And after he and Xu Rou get married, it is likely that he will go to the frontier again, and then Li Er is likely to let Xu Jingzong be responsible for providing salt to Tubo, and send another general to lead the army, he Zhang Yi may be a person in the middle at that time, the most difficult and most thankless kind.

But now Zhang Yi doesn't care about that, he doesn't want a high-ranking official position, nor does he want a high title, he just wants to finish these things as soon as possible and promote the Tang Dynasty to come soon.

When the Tang Dynasty entered the prosperous era, the Tang army was invincible in the world, and Li Er was not so difficult to do, he would be able to be idle, and at that time, he would be able to take his group of women and a group of children to stay in Zhangjiazhuang and enjoy the joy of family.

Just when Zhang Yi was constantly thinking about making plans, the carriage had already driven back to Zhangjiazhuang from Chang'an.

When Zhang Yi returned to Zhangjiazhuang, it was already noon, and the first thing he did when he returned to Zhangjiazhuang was not to have lunch with the old lady and others, but to walk directly back to the room and sleep!

He hasn't had a good rest in the past few days, from the night he came back from Shuofang City to the present, he has been in a state of nervous vigilance, and his whole person is tense, so that when he faces Li Er, he seems a little abnormal, less comfortable in the past and a little more hostile.

The old lady looked at Zhang Yi's tired appearance, and didn't let anyone call him, but just told Yun'er to get some food, and send it to his room for him to eat when Zhang Yi woke up.

in this world. No matter who it is, as long as it makes Zhang Yi unhappy, the old lady doesn't like it, even if it's Li Er, seeing Zhang Yi's tired appearance, the old lady is extremely angry, and she almost didn't open her mouth to scold Li Er.

But seeing Li Hui, the old lady couldn't help it again, no matter what, Li Er is her own father-in-law, but this father-in-law used his son-in-law a little hard.

The old lady didn't know about the current situation between Zhang Yi and Li Er, she was just imagining it out of thin air, and Zhang Yi didn't plan to tell them these things in order not to worry them.

Of course, the matter of the marriage given to him by the great Majesty Li Er still has to be said, and this matter will have to be done in a big way in the future, and it will definitely not be hidden.

The old lady must be happy to know about this, but Li Hui and the others don't know what kind of mood they are feeling.

Zhang Yi can only use Li Er as a shield, after all, His Majesty gave him a marriage, and he can't hide if he wants to, if you want to scold, you can go and scold Li Er, anyway, he is indeed very annoying.
